The action of the apparatus is as follows: The cylindrical or other shell to is supplied with sand to about the depth indicated in the drawings, and this sand being in direct contact with the shell a becomes highly heated. The shaft g is rotated by any suitable means the cylinder c,along which it is carried by the screw-conveyer f to the discharge-passage e. In the revolution of the cylinder 0 the pockets or lifters 0* lift up the heated sand and cause it to drop through the wire cloth of the cylinder 0, and through that of the screw-conveyer f onto and among the grain under treatment, whereby the said grain becomes quickly and uniformly heated until it has acquired the desired degree of roasting or drying, which may be regulated by varying the speed of the shaft 9, and, consequently the length of time occupied by the grain or cereal in passing through the cylinder 0, and during which it is submitted to heat therein.

Any sand thrown over by the pockets or lifters 0 against the shell a will pass into the side pockets, a, and be thereby kept for some little time against the inner face of the shell a, after which it will pass off at the bottom of such pockets a and mingle with the general bulk of sand in the shell a. The shaft g may, if desired, be formed hollow, to enable athermometer to be inserted, in order to ascertain the temperature within the cylinder 0.

By submitting the grain to the preliminary operation of washing or boiling, and then roasting or drying the same by the process and apparatus herein described, we are en abled to purify the grain and to produce roasted or dried grain which isfree from the bitter flavor it ordinarily possesses when roasted or dried without being submitted to a preliminary washing or boiling process.

\Ve are aware that it has been proposed to prepare grain for marketor other purposes by first subjecting it to the action of hot water and then to superheated steam, and do not claim, broadly, as our invention the process of treating grain which consists in first soaking in hot water and then drying.

Having now particularly described and ascertained the nature of our said invention and y in what manner the same is to be performed, at the required speed, and in its revolution it I we declare that what we claim is 1. The improved method of preparing grain or cereals, substantially as herein described, which consists in first subjecting it to the action of hot water and then drying it by commingling with a heated granular material, as set forth.

2. The method of roasting 0r drying grain or cereals by submitting the same to a bath of heated sand, substantially as herein shown and described, and for the purposes stated.

3. The combination, in apparatus for roasting or drying grain, of a shell, a, supplied with sand, side pockets, a, furnace b, wirecloth cylinder 0 c feeding-cylinder 0, pockets or lifters a, hopper (I, feed screw f, screwconveyer f, shaft and dischargeaperture e, substantially as herein shown and described, and for the purpose stated.
